The species from the subfamily Abietoideae usually grow as evergreen trees , only the golden larch ( Pseudolarix amabilis ) is deciduous. The leaves are needle-like.
All representatives are single-sexed ( monoecious ). The seed cones have no umbo and the cone scales have a narrow base. The brown seeds have a moderately tight wing. Resin bubbles can also be found on the seeds.
Systematics
The subfamily Abietoideae was set up in 1826 by Robert Sweet in Sweet's Hortus Britannicus: or a catalog of plants cultivated in the gardens of Great Britain, arranged in natural orders ... , page 372 as "Subordo Abietinae", although he gave no precise description. This only took place in a reverence written by Sweet to the work Commentatio Botanica de Conifereis et Cycadeis published by Louis Claude Marie Richard in September to November 1826 , in which this subfamily is listed as the Abietineae section .
There are six recent genera in the subfamily Abietoideae, two of which are monotypical , i.e. consist of only one species.
- Firs ( Abies Mill. ), Is the type genus for this subfamily.
- Cedars ( Cedrus Trew )
